SFR Definition 23.11. RCAPnH: Timer n Capture Register High Byte
SFR Definition 23.10. RCAPnL: Timer n Capture Register Low Byte
The RCAPnL register captures the low byte of Timer n when Timer n is configured in capture
mode. When Timer n is configured in auto-reload mode, it holds the low byte of the reload
value.
The RCAPnH register captures the high byte of Timer n when Timer n is configured in cap-
ture mode. When Timer n is configured in auto-reload mode, it holds the high byte of the
reload value.
The TMRnL register contains the low byte of the 16-bit Timer n
